Hence the common connected in' anysuitable way with some m0v 25 practice of locomotivia-engineersofshutting ing part .of. the machinery, is to force the oil off to createthe vacuum below the column l continuously into the diaphragm-chamber atto aid the steam-pressure above in blowing the side thereof above thediaphragm, so as out the oil-pipe. to continually force the same throughthe The primary object of this invention is to feed contraction13,.contr0llcd by the valve 30 avoid these defects and provide improved4-, and any oil in excess of that which may means for causing the oil tofeed automaticpass the valve 4 is automatically returned to ally anduniformly without subjecting the supthe oil-tank 12 when the pressure ofthe oil ply to the steam, so that no portion of the oil above thediaphragm, induced by the action will come in contact with thcsteamexcepting ot' the pump, exceeds the resistance of the 35 that which isbeing fed through the Feed coni diaphragm 7. This may be accomplished by5 I i l l traction or othcrpassagc that maybeprovided provii-ling theupper side of the diaphragm for dripping the oil from the supply or feedwith a suit-able valve 14, which, with dia valve to the place ofconsumption or use. phragin 7, constitutes a pressure-i'egulator andwhich under normal conditions closes an outlet 15, communicating by pipeor passage 9 1G with the supply-tank 12, but under abnor. malconditions, or when the supply of oil 01(- ceeds the consumption, isdrawn away from the outlet or relief passage 15, -iermitting the surplusoil to automatically escape back into I the supply-tank.
